CVE-2025-43732 in Liferay
Summary
by MITRE • 08/18/2025
Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.10, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.17 and 7.4 GA through update 92 is vulnerable to Insecure Direct Object Reference (IDOR) in the groupId parameter of the _com_liferay_roles_selector_web_portlet_RolesSelectorPortlet_groupId. When an organization administrator modifies this parameter id value, they can gain unauthorized access to user lists from other organizations.

The vulnerability identified as CVE-2025-43732 represents a critical Insecure Direct Object Reference flaw within Liferay Portal and Liferay DXP platforms affecting multiple version ranges. This weakness resides in the RolesSelectorPortlet component where the groupId parameter lacks proper authorization checks, allowing malicious actors to manipulate this parameter and access sensitive user data from organizations they should not be authorized to view. The vulnerability specifically impacts systems running Liferay Portal 7.4.0 through 7.4.3.132 and Liferay DXP versions spanning from 2025.Q1.0 through 2025.Q1.10, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.17, and all 7.4 GA releases through update 92. The technical implementation fails to validate whether the requesting user has legitimate access rights to the target organization's user data, creating a direct pathway for privilege escalation and unauthorized information disclosure.
This vulnerability operates at the application logic level and directly violates fundamental security principles of access control and authorization. The flaw manifests when an organization administrator attempts to modify the groupId parameter value, which should normally be restricted to prevent cross-organization data access. According to CWE-284, this represents an inadequate access control implementation where the system fails to properly enforce access restrictions on objects that should be protected from unauthorized access. The vulnerability enables attackers to enumerate user lists from different organizations by simply modifying the groupId parameter value, effectively bypassing the intended organizational boundaries within the Liferay platform's security model. This type of access control failure aligns with ATT&CK technique T1078.004 which covers valid accounts used for unauthorized access, as the attacker leverages existing administrative privileges to access data beyond their authorized scope.
The operational impact of this vulnerability extends beyond simple data exposure to encompass potential lateral movement within the organization's user management structure. An attacker with access to the RolesSelectorPortlet interface can systematically enumerate user accounts from multiple organizations by manipulating the groupId parameter, potentially discovering sensitive information such as employee details, roles, and access permissions across different organizational units. This capability undermines the fundamental principle of least privilege and organizational data segmentation that Liferay platforms are designed to enforce. The vulnerability is particularly concerning for organizations that rely on Liferay for multi-tenant environments or those with strict data isolation requirements, as it essentially provides a backdoor mechanism for unauthorized access to user data from other organizations within the same Liferay instance. The attack surface is relatively broad since this affects multiple version ranges and could be exploited by both internal and external threat actors who have access to the administrative interface.
Mitigation strategies for CVE-2025-43732 must focus on implementing proper input validation and authorization checks within the RolesSelectorPortlet component. Organizations should immediately apply the vendor-provided patches or updates that address this specific vulnerability, as the flaw requires code-level modifications to properly validate the groupId parameter against the user's organizational permissions. The recommended approach involves implementing robust access control mechanisms that verify the requesting user's authorization to access the specified organization's data before allowing any operations to proceed. Security teams should also consider implementing network-level restrictions to limit access to administrative interfaces and monitor for unusual parameter manipulation patterns in system logs. Additionally, organizations should conduct comprehensive access control reviews to ensure that all similar components within their Liferay environment properly validate object references and implement appropriate authorization checks. The mitigation process should include thorough testing to ensure that legitimate administrative functions continue to operate while preventing unauthorized cross-organizational data access, aligning with security best practices for preventing similar Insecure Direct Object Reference vulnerabilities in web applications.
